Benefits of technology

[0006]An object of the present invention is to provide a detection device of the kind mentioned in the preamble, that increases the possibilities to examine an object, and to facilitate navigating through the object when examining with a gamma camera.SUMMARY OF THE INVENTION

Problems solved by technology

Gamma cameras, in particular those which use so called pinholes, often have a (very) long scanning time, due to the relatively low sensitivity of the cameras.
This may be unfavourable for the object to be examined, in particular a test animal or human being, since movements during the scanning time have to be prevented as much as possible.
In both cases, this is associated with discomfort for the test animal or human being.
Often, gamma cameras with a high resolution have a small focusing volume, as a result of which “navigating” the focus volume is difficult.
This increases the scanning time unnecessarily.
The known system however has the disadvantage that it may not always be used, or at least not well, with many gamma detection systems.
In such a case in particular, there is little space for the optical cameras, for these can not be placed in the field of view of the gamma cameras.
Also, a good lighting of the object is very difficult in such case.

Embodiment Construction

[0095]FIG. 1 diagrammatically depicts a gamma detection device 1. This comprises a first or gamma detector 2 with two gamma cameras 3 and a gamma detection space 4. In it, there is a guide 8, along which an object holder 5 with an object 6 can be displaced by an object holder displacement means 7.

[0096]Additional cameras are designated by 10. Furthermore, a control device 12 is connected to a screen 14 for displaying a first image 16 and a second image 18, as well as to a keyboard 20.

[0097]The gamma detector 20 here has two gamma cameras 3. Of course, this could also be a single gamma camera. Preferably, there are even three, arranged in a triangle, since this allows a fine recording all around, with good 3D reconstruction possibilities, and yet with a simple configuration. Incidentally, it is remarked here that in this context, gamma camera means both a simple imaging device such as a pinhole camera, and a group of mutually associated imaging devices.

[0098]The object holder 5 may e...

Abstract

The invention provides a detection device and a method of making a gamma detection image.The detection device comprises a gamma camera and an additional camera, that can make an image of the object outside the gamma detection space. Through correlating the positions of the object with respect to the first and the second camera, the images therefrom may also be correlated.The correlation of the images allows quick and accurate navigation through the object.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a detection device and a method for making a gamma detection image.[0002]In a first aspect the invention relates to a detection device, comprising a first detector, a second detector, an object holder, an object holder displacement means, and a control device, wherein the first detector comprises a gamma detection space with a gamma camera having a first field-of-view that is located in the gamma detection space, the second detector comprises an additional camera that is sensitive to radiation that substantially differs from gamma radiation, and the control device comprises a screen.BACKGROUND OF THE INVENTION[0003]Gamma cameras, in particular those which use so called pinholes, often have a (very) long scanning time, due to the relatively low sensitivity of the cameras. This may be unfavourable for the object to be examined, in particular a test animal or human being, since movements during the scanning time have to be pr...
